Patient H.M. had his hippocampi surgically removed to treat epilepsy. After surgery, he could still remember events from his childhood but could not form new declarative memories. This case provides evidence that the hippocampus is essential for

A split-brain patient is shown an image of a key to the left visual field only. When asked what they saw, the patient says "nothing." However, when asked to pick up the object with their left hand, they correctly select the key. This demonstrates that
